So basically I'm trying to help a friend with her research project, unfortunately we have both failed to turn up any real info on Karyukai (the flower and willow world) other then one very short article...........and a harry potter fanfic......because why not?

All the other info focuses entirely on Geisha, which while part of her paper, is not the entirety of it. So ONRPG, know of any good sources?
